What is in banna pudding?

If you make your own pudding, the ingredients may include vanilla wafers, bananas, milk, eggs, vanilla extract, sugar, flour or starch, maybe a little salt.

You simply have bananas, vanilla wafers, and vanilla pudding. You can follow the ingredients on a pack of regular pudding (the kind you cook), or you can find a vanilla pudding recipe. Once you start cooking the pudding, you add sliced bananas and the wafers.
